First scholarly treatment of soil forming processes Johanna Döbereiner: 1924–2000: Brazil: Prominent Brazilian agronomist Vasily V. Dokuchaev: 1840–1903: Russia: Variously the father of modern soil science, pedology, soil geography Friedrich Albert Fallou: 1794–1877: Germany: Founder of modern soil science; coined the term "pedology" W ...
A soil scientist examining horizons within a soil profile. Soil science is the study of soil as a natural resource on the surface of the Earth including soil formation, classification and mapping; physical, chemical, biological, and fertility properties of soils; and these properties in relation to the use and management of soils.
Soil Profile on Chalk at Seven Sisters Country Park, England. Pedology (from Greek: πέδον, pedon, "soil"; and λόγος, logos, "study") is a discipline within soil science which focuses on understanding and characterizing soil formation, evolution, and the theoretical frameworks for modeling soil bodies, often in the context of the natural environment.

In his two books First Principles of Soil Science (1857, 2nd ed. 1865) and Pedology or General and Special Soil Science (1862) Friedrich Albert Fallou developed his collected field observations of soil into a systematic approach. He explained why soil formation was worthy of study and appealed for recognition of soil science as a discipline. In ...
Hans Jenny (7 February 1899 [1] – 9 January 1992 [2]) was a Swiss-born soil scientist and expert on pedology (the study of soil in its natural environment), particularly the processes of soil formation. He served as 1949 President of the Soil Science Society of America. [3]
American soil scientist Hans Jenny published in 1941 [128] a state equation for the factors influencing soil formation: S = f(cl, o, r, p, t, ...) S soil formation; cl (sometimes c) climate; o organisms (soil microbiology, soil mesofauna, soil biology) r relief; p parent material; t time; This is often remembered with the mnemonic Clorpt.
He explained why soil formation was worthy of study and appealed for recognition of soil science as a discipline. [5] [14] In the 1862 work, he presented a proposal for soil profile description, discussed the physical and chemical properties of soils, and proposed classification of soils based on mineral properties.

Soil science has two basic branches of study: edaphology and pedology. Edaphology studies the influence of soils on living things. [11] Pedology focuses on the formation, description (morphology), and classification of soils in their natural environment. [12]
